Peering down the neck of a round-bottom flask reveals crystals that look like the finale of a firework show spreading across a night sky. Nikhil Gaikwad, a research scholar at the National Institute of Pharmaceutical Education & Research, Hyderabad, came across these crystals of a chlorinated pyrrolopyrimidine while synthesizing potential anticancer agents. He generally uses dichloromethane to crystallize and purify his compounds after a chlorination reaction, but this time, Gaikwad decided to use chloroform. Instead of getting the usual needle-shape crystals, he was surprised to find these branching starbursts.
